HAY-LOADER.

S'PncrrrcA'rroN forming part of Letters Patent No. 659,382, datedoctober 9, 1900.

Application filed August 6. 1900. Serial No. 26.056. (No model.)

To all whom it may concern.-

Be it known that I, FRANK N. 'Tnissnn a citizen of the United States,residing at Dayton, in the county of Montgomery, State of Ohio, haveinvented certain new and useful Improvements in Hay-Loaders, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings, forming part of this specification.

My invention relates to machines for loading hay adapted to pick up thehay from the ground and elevate it to the wagon by means of forksattached to parallel bars, which bars are given a reciprocating and an up-and-down movement by their attachments to a crankshaft at right anglesto the bars.

The special purpose of my invention is to provide a simple, cheap, andeffective method for supporting this .crank-shaft at the center` toovercome the liability of the bending and twisting of the shaft, whichfrequently happens when it is supported and journaled only at the ends/This matter presents considerable difliculty from the fact that thecentral portion of the crank-shaft is inclined at an angle to the pointof desired support, so that where a central bearing has been desired ithas been customary to supply two shafts or to give an extra horizontalbend to the shaft at the center. It is. the object of my invention toprovide this center bearing and support without any modification orchange in the shaft itself, and this I accomplish by the specialconstruction to be hereinafter particf ularly pointed out and claimed..

In the drawings, Figure l is a perspective view of so much of thehay-loader as will illustrate my invention. Fig. 2 is a cross-section ofsame. Fig. 3 is a detail front elevation of the central hanger.A AYFig.4 is a side view of same. Fig. 5 is a front view of one of thecrank-shaft castings.

A is the bed-frame of the hay-loaderA of the usual description, acrosswhich is mounted the usual crank-shaft B, forming a number of cranksacross the frame. At the ends of these cranks are attached the vibratingrods O O, which rods carry forks on their lower sides, and by therotation of the crank-shaft.

in any well-known way the rods and forks are "ings to be rigidly securedto the shaft.

given a reciprocating and up-and-down movementv to pick up-and carryforward the hay to the upper end of the machine. This construction isold and well known and need not be further described. The bed-frame andits operating parts are mounted on carryingwheels, and the crank-shaftis usually rotated by sprocket wheel and chain connection with thecarrying-wheels of the loader. In order to obtain a central bearing forthis crank-shaft, I provide as follows:

D D are semicircular castings provided with ears a, et, by means ofwhich they may be bolted together to form a hub or fixed pulley Withfianges b b and central groove c. v A diagonal recess d is formed in theabutting faces of these castings D D to receive and fit around thecrank-shaft at its central point, and one of the castings is providedwith a lug c to t within a corresponding recess in the crank-shaft toprevent the castings from sliding on the shaft and to enable the cast-These castings are thus secured at the axial center of the crank-shaft,so that the pulley thus formed will rotate with the shaft, the axis ofthe shaft passing through the center of the wheel.

y E is a top brace supported in brackets F F to the sides of thebed-frame and extending across the frame in line with the plane of thecrank-shaft. Bolted to the middle of the top brace and dependingtherefrom are a pair of straps G G, curved around and fitting in thegroove c between the flanges b b of the pul- .ley and bolted together atthe'bottom, these straps thus forming a support and bearing for thepulley secured to the crank-shaft. In

this way a perfect support is obtained for the IOS) shaft, and a dividedstrap forming a bearing IO for said pulley, With a cross-brace supportedon the frame to which said strap is secured, substantially as shown anddescribed.
